Pedro Jaime Martínez, (born October 25, 1971), is a Dominican–American[1] former starting pitcher in Major League Baseball who played for five teams from 1992 to 2009, most notably the Boston Red Sox. From 2002 to 2006 he held the major league record for the highest career winning percentage by a pitcher with at least 200 decisions; with a final record of 219 wins and 100 losses, he retired with the fourth-highest percentage in history, and the highest by a right-hander since the modern pitching era began in 1893.[2] He ended his career with an earned run average (ERA) of 2.93, the sixth-lowest by a pitcher with at least 2,500 innings pitchedsince 1920. Martínez reached the 3,000 strikeout mark in fewer innings than any pitcher except Randy Johnson, and is the only pitcher to compile over 3,000 strikeouts with less than 3,000 innings pitched; his career strikeout rate of 10.04 per 9 innings trails only Johnson (10.61) among pitchers with over 1,500 innings.

An eight-time All-Star, Martínez was at his peak in the years from 1997 to 2003, establishing himself as one of the most dominant pitchers in history.[3][4][5][6][7] He won three Cy Young Awards (1997, 1999, 2000) and was runner-up twice (1998, 2002), posting a cumulative record of 118–36 (.766) with a 2.20 ERA while leading his league in ERA five times and in winning percentage and strikeouts three times each. In 1999 he was runner-up for the American League (AL) Most Valuable Player Award after winning the pitching Triple Crown with a 23–4 record, 2.07 ERA and 313 strikeouts, and – along with Johnson – joined Gaylord Perry and Roy Halladay in the rare feat of winning the Cy Young Award in both the American and National Leagues. He is also the record holder for the lowest single-season WHIP in major league history with 0.737, doing so in 2000. Although his performance suffered a steep decline in 2004, he ended the season memorably by helping the Red Sox end a long drought in winning their first World Series title in 86 years.

Officially listed at 5 ft 11 in (1.80 m) and 170 pounds (77 kg), Martínez was unusually small for a modern-day power pitcher, and is believed to have been somewhat smaller than his officially listed height and weight.[8] In his early 30s, injuries began to keep him off the field to an increasing extent, with his appearances and success dropping off sharply in his final seasons. Modern sabermetric analysis has strongly highlighted Martínez' achievements; his WHIP is the lowest of any live-ball era starting pitcher, his adjusted ERA+ is the best of any starting pitcher in major league history,[9] and he has the third-highest strikeout-to-walk ratio in modern history. He dominated while pitching most of the time in a hitter-friendly environment and facing some of the toughest competition during the so-called steroid era, which is generally thought to have favored batters.[10][11][12][13] He was elected to the Baseball Hall of Fame in 2015, his first year of eligibility, joining Juan Marichal as the second Dominican to be enshrined; his number (45) was retired by the Red Sox in a ceremony two days after his Hall induction.[14]

Martínez grew up in the Dominican Republic in the Santo Domingo suburb of Manoguayabo. He was the fifth of six siblings living in a palm wood house with a tin roof and dirt floors. His father, Pablo Jaime Abreu,[note 1] worked odd jobs. His mother, Leopoldina Martínez, worked for traditionally wealthy families, washing their clothes. When Pedro was old enough to work, he held a job as a mechanic.[16]

He did not have enough money to afford baseballs, so he improvised with oranges. His older brother, Ramón Martínez, was pitching at a Los Angeles Dodgers baseball camp in the Dominican Republic. As a young teenager, Martínez carried his brother's bags at the camp. One day at the camp, Ramón Martínez clocked his 14-year-old brother's pitches at between 78 and 80 miles per hour.[17]

Martínez was originally signed by the Dodgers as an amateur free agent in 1988. After pitching in the Dodgers farm system for several years, he made his MLB debut on September 24, 1992 for the Dodgers against the Cincinnati Reds, working two scoreless innings of relief. He made his first start for the Dodgers on September 30, taking the loss while giving up two runs in a 3–1 loss to the Reds.

Although Pedro's brother Ramón, then a star pitcher for the Dodgers, declared that his brother was an even better pitcher than he, the younger Martínez was thought by manager Tommy Lasorda too small to be an effective starting pitcher at the MLB level; Lasorda used Pedro Martínez almost exclusively as a relief pitcher.[19] Lasorda was not the first to question Martínez's stature and durability; in the minor leagues, the then-135-pound pitcher was threatened with a $500 fine if he was caught running. Martínez turned in a strong 1993 season as the Dodgers' setup man, going 10–5 with a 2.61 ERA and 119 strikeouts, in 65 games; his 107 innings led all NL relievers.[20] With the Dodgers in need of a second baseman after a contract dispute with Jody Reed, Martínez was traded to the Montreal Expos for Delino DeShields before the 1994 season.

It was with the Expos that he developed into one of the top pitchers in baseball. On April 13, 1994, Martínez took a perfect game through 71⁄3 innings until throwing a brushback pitch at Reggie Sanders led Sanders to immediately charge the mound, starting a bench-clearing brawl. Martínez ended up with a no-decision in the game, which the Expos eventually won 3–2.

On June 3, 1995, Martínez pitched nine perfect innings in a game against the San Diego Padres, before giving up a hit in the bottom of the 10th inning. He was immediately removed from the game, and was the winning pitcher in Montreal's 1–0 victory. [See Memorable Games]

In 1996, during a game against the Philadelphia Phillies, Mike Williams attempted to hit Martínez with retaliatory pitches for an earlier hit batter but failed with two consecutive attempts. After the second attempt, Martínez charged the mound, and started a bench-clearing fight.

In 1997, Martínez posted a 17–8 record for the Expos, and led the league in half a dozen pitching categories, including a 1.90 ERA, 305 strikeouts and 13 complete games pitched, while becoming the only Expo ever to win the National LeagueCy Young Award. The 13 complete games were tied for the second-highest single-season total in all of baseball since Martínez's career began (Curt Schilling had 15 in 1998; Chuck Finley and Jack McDowell also reached 13 in a year). However, this 1997 total is by far the highest in Martínez's career, as he only completed more than 5 games in one other season (7, in 2000). Martínez was the first right-handed pitcher to reach 300 strikeouts with an ERA under 2.00 since Walter Johnson in 1912.

Approaching free agency, Martínez was traded to the Boston Red Sox in November 1997 for Carl Pavano and Tony Armas, Jr., and was soon signed to a six-year, $75,000,000 contract (with an option for a seventh at $17 million) by Red Sox general manager Dan Duquette, at the time the largest ever awarded to a pitcher. Martínez paid immediate dividends in 1998, with a 19–7 record, and finishing second in the American League in ERA, WHIP, strikeouts, and the Cy Young voting.

In 1999, Martínez finished 23–4 with a 2.07 ERA and 313 strikeouts (earning the pitching Triple Crown), unanimously winning his second Cy Young Award (this time in the American League), and coming in second in the Most Valuable Player (MVP) ballot.[citation needed][21] The MVP result was controversial, as Martínez received the most first-place votes of any player (8 of 28), but was omitted from the ballot of two sportswriters, New York's George King and Minneapolis' LaVelle Neal. The two writers argued that pitchers were not sufficiently all-around players to be considered. (However, George King had given MVP votes to two pitchers just the season before: Rick Helling and David Wells; King was the only writer to cast a vote for Helling, who had gone 20–7 with a 4.41 ERA and 164 strikeouts.) MVP ballots have ten ranked slots, and sportswriters are traditionally asked to recuse themselves if they feel they cannot vote for a pitcher. "It really made us all look very dumb", said Buster Olney, then a sportswriter for the New York Times. "People were operating under different rules. The question of eligibility is a very basic thing. People were determining eligibility for themselves."[22]The Times does not permit its writers to participate in award voting. Martínez finished second to Texas Rangers catcher Iván Rodríguez, by a margin of 252 points to 239. Rodríguez had been included on all 28 ballots. When asked about the result by WEEI-FM radio in January 2012, Martínez said, "I'm not afraid to say that the way that George King and Mr. LaVelle Neal III went about it was unprofessional."[23]

Between August 1999 and April 2000, Martínez had ten consecutive starts with 10 or more strikeouts. Only three pitchers have had as many as seven such starts in a row, and one of those was Martínez himself, in April–May 1999. He averaged more than 15 strikeouts per nine innings during his record 10-game streak.[24] During the 1999 season, he set the record for most consecutive innings pitched with a strikeout, with 40. For his career, Martínez has compiled 15 or more strikeouts in a game ten times, which is tied with Roger Clemens for the third-most 15-K games in history. (Nolan Ryan had 27, and Randy Johnson had 29.)

Martínez was a focal point of the 1999 playoffs against the Cleveland Indians. Starting the series opener, he was forced out of the game after 4 shutout innings due to a strained back with the Red Sox up 2–0. The Red Sox, however, lost the game 3–2. Boston won the next two games to tie the series, but Martínez was still too injured to start the fifth and final game. However, neither team's starters were effective, and the game became a slugfest, tied at 8–8 at the end of 3 innings. Martínez entered the game as an emergency relief option. Unexpectedly, Martínez neutralized the Cleveland lineup with six no-hit innings for the win. He struck out eight and walked three, despite not being able to throw either his fastball or changeup with any command. Relying totally on his curve, Martínez and the Red Sox won the deciding game 12–8.

Following up 1999, Martínez had perhaps his best year in 2000. Martínez posted an exceptional 1.74 ERA, the AL's lowest since 1978, while winning his third Cy Young Award. His ERA was about a third of the park-adjusted league ERA (4.97). No other single season by a starting pitcher has had such a large differential. Roger Clemens' 3.70 was the second-lowest ERA in the AL, but was still more than double that of Martínez. Martínez also set a record in the lesser known sabermetric statistic of Weighted Runs allowed per 9 innings pitched (Wtd. RA/9), posting a remarkably low 1.55 Wtd. RA/9. He gave up only 128 hits in 217 innings, for an average of just 5.31 hits allowed per 9 innings pitched: the third lowest mark on record.

Martínez's record was 18–6, but could have been even better. In his six losses, Martínez had 60 strikeouts, 8 walks, and 30 hits allowed in 48 innings, with a 2.44 ERA and an 0.79 WHIP, while averaging 8 innings per start. Martínez's ERA in his losing games was less than the leading ERA total in the lower-scoring National League (Kevin Brown's 2.58). The Yankees' Andy Pettitte outdueled Martínez twice; Martínez's other four losses were each by one run. Martínez's first loss of the year was a 1–0 complete game in which he had 17 strikeouts and 1 walk. All of Martínez's losses were quality starts, and he pitched 8 or more innings in all but one of his losses. Martínez received 2 runs or fewer of run support in 10 of his starts (over one third of his starts), in which his ERA was a minuscule 1.25 with 4 complete games and 2 shutouts, but his win-loss record was 4–5.

Martínez's WHIP in 2000 was 0.74, breaking both the 87-year-old modern Major League record set by Walter Johnson, as well as Guy Hecker's mark of 0.77 in 1882. The American Leagueslugged just .259 against him. Hitters also had a .167 batting average and .213 on-base percentage, setting two more modern era records. Martínez became the only starting pitcher in history to have more than twice as many strikeouts in a season (284) as hits allowed (128). Martínez also set an American League record in K/BB, with a ratio of 8.88, surpassing the previous record set by Martínez in 1999 of 8.46.

On May 6 of that 2000 season, Martínez struck out 17 Tampa Bay Devil Rays in a 1–0 loss. In his next start six days later, he struck out 15 Baltimore Orioles in a 9–0, two-hit victory. The 32 strikeouts tied Luis Tiant's 32-year American League record for most strikeouts over two games.

In the span of 1999 and 2000, Martínez allowed 288 hits and 69 walks in 430 innings, with 597 strikeouts, an 0.83 WHIP, and a 1.90 ERA. Some[6] statisticians believe that in the circumstances — with lefty-friendly Fenway Park as his home field, in a league with a designated hitter, during the highest offensive period in baseball history — this performance represents the peak for any pitcher in baseball history.

Though he continued his dominance when healthy, carrying a sub-2.00 ERA to the midpoint of the following season, Martínez spent much of 2001 on the disabled list with a rotator cuff injury as the Red Sox slumped to a poor finish. Martínez finished with a 7–3 record, a 2.39 ERA, and 163 strikeouts, but only threw 116 innings.

Healthy in 2002, he rebounded to lead the league with a 2.26 ERA, 0.923 WHIP and 239 strikeouts, while going 20–4. However, that season's American League Cy Young Award narrowly went to 23-game winner Barry Zito of the Oakland A's, despite Zito's higher ERA, higher WHIP, fewer strikeouts, and lower winning percentage. Martínez became the first pitcher since the introduction of the Cy Young Award to lead his league in each of those four statistics, yet not win the award.

Martínez's record was 14–4 in 2003. He led the league in ERA for the fifth time with 2.22, also led in WHIP for the fifth time at 1.04, and finished second to league leader Esteban Loaiza by a single strikeout. Martínez came in third for the 2003 Cy Young Award, which went to Toronto's Roy Halladay.

Martínez went 16–9 in 2004, despite an uncharacteristic 3.90 ERA, as the Red Sox won the American League wild card berth. He pitched effectively in the playoffs, contributing to the team's first World Series win in 86 years. Martínez again finished second in AL strikeouts, and was fourth in that winter's Cy Young voting.

The seven-year contract he received from the Red Sox had been considered a huge risk in the 1997 offseason, but Martínez had rewarded the team's hopes with two Cy Young Awards, and six Top-4 finishes. Martínez finished his Red Sox career with a 117–37 record, the highest winning percentage any pitcher has had with any team in baseball history.

After Boston's World Series triumph in 2004, Martínez became a free agent and signed a 4-year, $53 million contract with the New York Mets. In 2005, his first season as a Met, Martínez posted a 15–8 record with a 2.82 ERA, 208 strikeouts, and a league-leading 0.95 WHIP. It was his sixth league WHIP title, and the fifth time that he led the Major Leagues in the category. Opponents batted .204 against him.

Martínez started the 2006 season at the top of his game. At the end of May, he was 5–1 with a 2.50 ERA, with 88 strikeouts and 17 walks and 44 hits allowed in 76 innings; Martínez's record was worse than it could have been, with the Mets bullpen costing him two victories. However, during his May 26 start against the Florida Marlins, Martínez was instructed by the umpires to change his undershirt. He slipped in the corridor, injuring his hip, and his promising season curdled. The effect was not immediately apparent; although Martínez lost the Marlins game, his following start was a scintillating 0–0 duel with Arizona's Brandon Webb. But after that, beginning on June 6, Martínez went 4–7 with a 7.10 ERA in a series of spotty starts interrupted twice by stays on the disabled list. A right calf injury plagued him for the last two months of the season. After Martínez was removed from an ineffective September 15 outing, television cameras found him in the Mets dugout, apparently crying.[26] Subsequent MRI exams revealed a torn muscle in Martínez's left calf, and a torn rotator cuff. Martínez underwent surgery which sidelined him for most of the 2007 season.[27]

Martínez with the Mets

On November 3, 2006, Martínez stated that if he could not return to full strength, he might end up retiring after the 2007 season. "It's getting better, and progress is above all what is hoped for", Martínez told the Associated Press. "To go back, I have to recover, I have to be healthy. But if God doesn't want that, then I would have to think about giving it all up." Martínez added, "It's going to be a bitter winter because I am going to have to do a lot of work. The pain I feel was one of the worst I have felt with any injury in my career." But by December 30, 2006, Martínez was more optimistic: "The progress has been excellent. I don't have problems anymore with my reach or flexibility, and so far everything is going very well. The problem has to do with the calcification of the bone that was broken with the tear, and that had to be operated on. You have to let it run its course." Martínez also reported bulking up as part of his recuperative regimen: "I've put on about 10 pounds of muscle, because that's one of our strategies."[28]

On September 3, 2007, Martínez returned from the disabled list with his 207th career win, allowing two earned runs in five efficient innings and collecting his 3000th career strikeout, becoming the 15th pitcher to do so. "I thought I was going to have butterflies and like that", said Martínez, "but I guess I'm too old." Martínez's comeback was considered a great success, as the right-hander went 3–1 in five starts with a 2.57 ERA. But his last start was a crucial 3–0 loss to St. Louis in the final week of the 2007 Mets' historic collapse; Martínez provided a good pitching performance (7 IP, 2 ER, 7 H, 1 BB, 8 K) but his teammates failed to score.

Martínez became just the fourth pitcher to reach 3,000 strikeouts with fewer than 1,000 walks (in Martínez's case, 701). Ferguson Jenkins, Greg Maddux and Curt Schilling had previously done likewise. Martínez also joined Nolan Ryan and Randy Johnson to become the third 3,000-strikeout pitcher to have more strikeouts than innings pitched, and is also the first Latin American pitcher to have 3,000 strikeouts.

His unexpectedly strong finish in 2007 raised hopes, but 2008 was a lost season for Martínez. He was injured just four innings into his first game of the season, an April 1 no-decision against the Florida Marlins. He later told reporters he'd felt a "pop" in his left leg. Martínez was diagnosed with a strained hamstring[29] and did not return to action for more than two months. Following his return, his fastball typically topped out in the 90–91 mph range,[30] a lower velocity than he'd had during his prime but slightly higher than in recent seasons. Martínez finished the season on a low note, losing all three of his decisions in September en route to a 5–6 record, the first losing record of his career. (Martínez was 0–1 in two appearances in 1992.) His 5.61 ERA and 1.57 WHIP were also Martínez's worst ever, and for the first time in his career, he failed to strike out at least twice as many batters as he walked (87–44).

During his four-year Met contract, Martínez was 32–23 in 79 starts, with a 3.88 ERA and a 1.16 WHIP.

A free agent, Martínez did not sign with a major league team during the winter. In March, he joined the Dominican Republic's squad for the 2009 World Baseball Classic, in an attempt to showcase his arm. Martínez pitched six scoreless innings with 6 strikeouts and no walks, but the team was quickly eliminated from the tournament and no MLB contract was forthcoming. In July 2009, Phillies scouts evaluated Martínez in two simulated games against the Phillies DSL team, leading to a one-year, $1-million contract.[31] Martínez told reporters, "I would just like to be the backup. If I could be the backup, that would be a great thing to have—a healthy Pedro behind everybody else, in case something happens. That would be a great feeling to have on a team, eh?"[32]

Martinez pitching during his brief stint with the Phillies in 2009

Replacing Jamie Moyer as a starter in the Phillies rotation on August 12, Martínez won his 2009 debut. In his return to New York on August 23, Martínez's win against the Mets was preserved by a rare unassisted triple play by second baseman Eric Bruntlett in the bottom of the ninth inning. With his win on September 3—his third as a Philadelphia Phillie and his 100th as a National Leaguer—Martínez became the 10th pitcher in history to win at least 100 games in each league.[33][34] On September 13, Martínez pitched eight innings to beat the Mets again, by a final score of 1–0. His 130 pitches were the most he had thrown in a game since the ALDS in October 2003. Philadelphia won each of Martínez's first seven starts, the first time in franchise history that this had occurred with any debuting Phillies pitcher.[35] In the NLCS against the Los Angeles Dodgers, he pitched seven shutout innings while allowing just two hits, but the Philadelphia bullpen faltered in the following inning, costing Martínez the win.

Intense media interest preceded Martínez's "return to Yankee Stadium" in Game 2 of the World Series. At the pre-game press conference, he seemed to relish the attention, telling reporters, "When you have 60,000 people chanting your name, waiting for you to throw the ball, you have to consider yourself someone special, someone that really has a purpose out there."[36] Martínez pitched effectively in his second-ever World Series start, but left the game in the 7th inning trailing, 2–1, and wound up taking the loss. Before his second start of the Series, Martínez called himself and opposing pitcher Andy Pettitte "old goats", and acknowledged that Red Sox fans were rooting for him: "I know that they don't like the Yankees to win, not even in Nintendo games."[37] However, Martínez allowed 4 runs in 4 innings, falling to 0–2 as the Phillies lost the sixth game and the 2009 World Series to the New York Yankees.

Following the Series, Martínez announced that he had no intention of retiring,[38] but the 2010 season came and went without his signing with a team. Media reports surfaced that the Phillies had been discussing a deal to bring Martínez back for another half-season,[39] but Martínez's agent announced in July that he would not be pitching at all in 2010, while remaining interested in a 2011 return.[40] In December 2010, Martínez told a reporter for El Día "I'm realizing what it is to be a normal person. ... It's most likely that I don't return to active baseball ... but honestly I don't know if I'll definitively announce my retirement."[41] The pitcher received some initial inquiries during the winter, but did not sign with any team for 2011. On December 4, 2011, he officially announced his retirement.

On January 24, 2013, Martínez joined the Boston Red Sox as a special assistant to general manager Ben Cherington.[43]

Martínez was elected to the National Baseball Hall of Fame in January 2015 with 91.1% of the votes. His Hall of Fame plaque will have the cap of the Boston Red Sox. "I cannot be any prouder to take Red Sox Nation to the Hall of Fame with the logo on my plaque", Martínez said in a statement. "I am extremely proud to represent Boston and all of New England with my Hall of Fame career. I'm grateful to all of the teams for which I played, and especially fans, for making this amazing honor come true."[44]

On June 22, 2015, it was announced that Martínez' number 45 would be retired by the Red Sox on July 28, two days after his Hall of Fame induction. Red Sox principal owner John Henry stated, "to be elected into the Baseball Hall of Fame upon his first year of eligibility speaks volumes regarding Pedro’s outstanding career, and is a testament to the respect and admiration so many in baseball have for him."[48]

On April 13, 1994, in his second start as a Montreal Expo, Martínez lost a perfect game with one out in the eighth inning when he hit Cincinnati's Reggie Sanders with a pitch. An angered Sanders charged the mound, and threw Martínez to the ground, before both teams cleared the benches and broke up any potential fight. Sanders was later ridiculed in the press for assuming that a pitcher would abandon a perfect game in order to hit a batter intentionally. Martínez allowed a leadoff single in the ninth inning, breaking up his no-hitter, and was removed for reliever John Wetteland (who loaded the bases, then allowed two sacrifice flies, thus saddling Martínez with a no-decision).[49] Three years later, in 1997, Martínez had a one-hitter against the Reds; the one hit came in the 5th inning.[50]

On June 3, 1995, while pitching for Montreal, he retired the first 27 Padres hitters he faced. However, the score was still tied 0–0 at that point and the game went into extra innings. The Expos scored a run in the top of the 10th, but Martínez surrendered a double to the 28th batter he faced, Bip Roberts. Expos manager Felipe Alou then removed Martínez from the game, bringing in reliever Mel Rojas, who retired the next three batters.[51] Martínez officially recorded neither a perfect game nor a no-hitter. Until 1991, the rules would have judged it differently; however, a rule clarification specified that perfect games, even beyond nine innings, must remain perfect until the game is completed for them to be considered perfect. This retroactively decertified many no-hit games, including Ernie Shore's perfect relief stint in 1917 and Harvey Haddix's legendary 12 perfect innings in 1959 (lost in the 13th).

Martínez was selected as the starting pitcher for the American LeagueAll-Star team in 1999. The game, on July 13, 1999, was at Fenway Park, Martínez's home field. Martínez struck out Barry Larkin, Larry Walker, and Sammy Sosa consecutively in the first inning. He then struck out Mark McGwire leading off the 2nd, becoming the first pitcher to begin an All-Star game by striking out the first four batters. (The National League's Brad Penny matched the feat in 2006.) The next batter, Matt Williams, managed to reach first base from an error by Roberto Alomar. Martínez then proceeded to strike out Jeff Bagwell while Williams was caught stealing.

Martínez again came close to a perfect game on September 10, 1999, when he beat the New York Yankees, 3–1. He faced just 28 batters while striking out 17 and walking none (Martínez hit the Yankees' first batter, Chuck Knoblauch, but he was then caught stealing). Only a solo home run by Chili Davis separated Martínez from a no-hitter. The Davis home run came in the second inning, eliminating any suspense, but this may have been Martínez's most dominant day on the mound.[52] Sportswriter Thomas Boswell called it the best game ever pitched at Yankee Stadium.[53]

On October 11, 1999, in Game 5 of the ALDS, Charles Nagy started for Cleveland and Bret Saberhagen started for Boston, both on only three days rest. Boston jumped out to a quick two-run lead in the top of the first inning, but Cleveland responded with three runs of their own in the bottom half of the innings. The hitting would continue impressively, knocking Saberhagen out of the game after only one inning pitched and five runs allowed, and Nagy out of the game after only three innings pitched and eight runs allowed. Going into the fourth inning, manager Jimy Williams opted to replace Derek Lowe with the ailing Pedro Martínez, who had left Game 1 with a back injury. This decision would prove to be wise, as Martínez threw six hitless innings in relief to win the final game of the ALDS, a performance detailed above.[54]

Game 3 of the American League Championship Series was the long anticipated matchup between Pedro Martínez and Roger Clemens. The Red Sox scored first. After a leadoff triple by Offerman, Valentin homered to put the Red Sox ahead 2–0. The onslaught continued as the Red Sox scored in all but two innings. Clemens was done in the third inning and the Red Sox would go on to win 13–1 and make the series two games to one. When Clemens was knocked out, Red Sox fans chanted "Where is Roger?" and then a response chant of "In the Shower". Martínez struck out twelve Yankees in seven scoreless innings and allowing just two hits, to beat Red Sox nemesis Roger Clemens and the New York Yankees in Game 3, handing the World Champions their only loss of the 1999 postseason. Martínez finished 1999 with a streak of seventeen scoreless innings in the playoffs.

On May 28, 2000, Martínez and Roger Clemens had a dramatic duel on ESPN's "Sunday Night Baseball" telecast. Both pitchers shone, combining to allow only 9 hits and 1 walk while striking out 22. A 0–0 game was finally broken up in the 9th inning by Trot Nixon's home run off Clemens. In the bottom of the ninth, the Yankees loaded the bases against a tiring Martínez, but New York could not score, as Martínez completed the shutout.[55]

On August 29, 2000, Martínez took a no-hitter into the 9th against the Tampa Bay Devil Rays, losing it on a leadoff single by John Flaherty. Martínez had begun the night by hitting the leadoff batter, Gerald Williams, in the hand. Williams started towards first base before charging the mound and knocking down Martínez; in the scrum, Williams was tackled by Boston catcher Jason Varitek. Martínez then retired the next 24 hitters in a row until allowing Flaherty's single, and finished with a one-hitter. He had 13 strikeouts and no walks in the game; the Flaherty single would have broken up a perfect game, if not for the leadoff hit batsman.[56] Pedro Martínez never threw an official no-hitter. He did however throw a combined perfect game in Spring training earlier that year on March 15, 2000.[57] He has though professed a lack of interest in the matter: "I think my career is more interesting than one game."

In the testy Game 3 of the 2003 ALCS, after allowing single runs in the 2nd, 3rd, and 4th innings, Martínez hit Yankees right fielderKarim García near the shoulders with a pitch, sparking a shouting match between Martínez and the New York bench. Directing his attention at Yankees catcher Jorge Posada, Martínez jabbed a finger into the side of his own head, which some, including an enraged Yankee bench coachDon Zimmer, interpreted as a threatened beanball. Emotions remained high in the bottom of the inning, which was led off by Boston slugger Manny Ramírez. Ramirez became irate over a high strike from Roger Clemens, and both benches cleared. During the ensuing commotion, the 72-year-old Zimmer ran towards Martínez in an attempt to knock him down; Martínez sidestepped Zimmer and threw him to the ground by his head.[58] Later, Martínez claimed that he was not indicating that he would hit Posada in the head, but that he would remember what Posada was saying to him.[59] In 2009, Martínez claimed that he regretted the incident but denied being at fault. Zimmer did not give much credence to Pedro's statements.[60] Martínez wrote in 2015 that the altercation with Zimmer was his only regret of his entire career.[61]

Martínez was also on the mound for Game 7 of the 2003 ALCS versus the Yankees. With the Red Sox ahead 5–2 at the start of the 8th inning, a tiring Martínez pitched his way into trouble. He was visited on the mound by manager Grady Little, but was left in to pitch, in a controversial non-move. The Yankees tied the score against Martínez in that inning on four successive hits, leading to a dramatic extra-inning, series-ending victory for New York, costing Grady Little his job with the Red Sox as his contract was not renewed.[62]

After a comparatively lackluster season in 2004 (though still a solid season by general standards), Pedro Martínez got the win in Game 3 of the World Series. He shut out the St. Louis Cardinals through seven innings, recording his final 14 outs consecutively in what would turn out to be his last game for Boston.[63]

With the Mets, on April 10, 2005, at Turner Field, Martínez outdueled John Smoltz, pitching a two-hit, one-run, complete game en route to his first Mets victory. On August 14, 2005, against the Dodgers, he pitched 71⁄3 hitless innings, but ended up losing the no-hitter and the game.[64]

In June 2006, the Mets played an interleague series against the Red Sox, which was Martínez's first appearance at Fenway Park since leaving the team. The Red Sox gave their former ace a two-minute video tribute on June 27, but showed no courtesies to Martínez the following night. In his June 28, 2006 start, Martínez lasted only 3 innings, and was rocked for 8 runs (6 earned) on 7 hits, losing his worst game as a Met just before going onto the disabled list.[65] It was Martínez's only career appearance against the Red Sox, the only Major League team against which he did not record a victory.

In both the 2004 ALCS and the 2009 World Series, Martinez was greeted with the chant "Who's your daddy?" from New York Yankees fans whenever Pedro was pitching due to his statement earlier in the 2004 ALCS saying, "They beat me. They're that good right now. They're that hot. I just tip my hat and call the Yankees my daddy."

"I'm not afraid of hitting anyone, because I can put the ball where I want to. I only hit nine guys last year. When I do hit them, it's usually just a nibble. I can nibble their jersey with the ball. That's how much I can control the ball."

Martínez's pitching style was atypical as he commanded an arsenal of "out" pitches. His fastball, slider, curveball and circle changeup were all well above average; combined with his historically excellent control, they proved to be an overpowering package. Martínez threw from a low three-quarters position (nearly sidearm) that hid the ball very well from batters, who have remarked on the difficulty of picking up Martínez's delivery. Additionally, Martínez threw three different types of fastballs - a straight high-velocity four-seam fastball he used to overpower hitters, a two-seamer that ran to his throwing arm side, and a cut fastball that ran away from his throwing arm side - each with the pinpoint control that defined him.

Early in his career, Martínez's fastball was consistently clocked in the 95–97 mph range. Using it in combination with his devastating changeup and occasionally mixing in his curveball, he was as dominant a pitcher as the game has ever seen. Sports Illustrated's Joe Posnanski wrote, "There has never been a pitcher in baseball history—not Walter Johnson, not Lefty Grove, not Sandy Koufax, not Tom Seaver, not Roger Clemens—who was more overwhelming than the young Pedro."[67]

As injuries and the aging process took their toll, Martínez made the adjustment to rely more on finesse than power. His fastball settled into the 85–88 mph range, although he was able to occasionally reach 90–91 mph when the need arose. Martínez continued to use a curveball, a circle changeup, and an occasional slider. With his command of the strike zone, he remained an effective strikeout pitcher despite the drop in velocity. Baseball historian Bill James described Martínez as being substantially more effective than his pitching peers due to his variety of pitches, pitch speeds, pinpoint control, and numerous modes of deception.[citation needed][68]
